# Anthropic Organization Deletion
Organization deletion and bulk delete remove tenant data, projects, and member access in a single administrative action.
An attacker can use this to break AI-assisted workflows as an impact technique, to extort the organization, or to
destroy evidence after finishing a data export. Once deletion progresses, recovery options shrink and earlier
exfiltration activity is harder to reconstruct from the tenant itself.

## Investigation guide


## Triage and analysis


### Investigating Anthropic Organization Deletion

Organization deletion / bulk delete removes tenant data, projects, and member access. Treat early actions as urgent —
recovery options shrink as the workflow progresses.
Unauthorized = no offboarding / lab-teardown ticket naming this org and actor, or deletion preceded by owner transfer,
admin grants, key creation, or data exports without a matching business project.

#### Possible investigation steps

- Identify actor (`user_actor` → email/IP/UA) and `organization.id`.
- Urgency by action:
  - `org_deletion_requested`: intervene immediately if unauthorized.
  - `org_bulk_delete_initiated`: bulk delete started — escalate IR now.
  - `org_deleted_via_bulk`: completed — prioritize evidence preservation outside the tenant.
- Look for preceding primary owner transfer, admin grants, admin API key creation, or data exports.
- Close as FP only when platform owners confirm scheduled decommission with matching ticket/time/actor.


### False positive analysis

- Sandbox teardown and contract termination are valid — require change management or offboarding records.


### Response and remediation

- On unauthorized activity: engage Anthropic support and internal IR immediately, preserve remaining audit logs
  (including prior exports), and rotate administrative credentials for the organization.


## Rule Query

```esql
from logs-anthropic.audit-* metadata _id, _version, _index
| where
    data_stream.dataset == "anthropic.audit" and
    mv_contains(event.category, "configuration") and
    event.action in ("org_deletion_requested", "org_bulk_delete_initiated", "org_deleted_via_bulk")
| keep _id, _version, _index, @timestamp, event.*, organization.*, user.*, source.*, user_agent.*, anthropic.audit.*, data_stream.*
```
